ITap Index Finger Tap Interaction by Gaze and Tabletop Integration

This dataset contains experimental results evaluating ITap, a novel index finger tap interaction technique that integrates gaze-based object selection with tabletop touch gestures. The dataset includes Task Completion Time (TCT), Error Rate, System Usability Scale (SUS) scores, and NASA-TLX workload scores obtained from user studies.<br>1. Task Completion Time (TCT)TCT represents the time taken by participants to complete each interaction task using ITap.The dataset provides TCT values measured across different target distances and interaction scenarios.2. Error RateThe error rate measures the number of incorrect selections or unintended interactions per trial.It helps assess the precision and reliability of the ITap method compared to alternative selection techniques.3. System Usability Scale (SUS) ScoresThe SUS is a widely used usability assessment questionnaire.<br>4. NASA-TLX Workload ScoresNASA-TLX is a subjective workload assessment tool used to measure the cognitive and physical demands of ITap.It includes six subscales: mental demand, physical demand, temporal demand, performance, effort, and frustration.The dataset provides NASA-TLX ratings to evaluate the overall user burden when using ITap.
